Abstract
A multiple-needle sewing machine has a presser foot and first and second feed dogs for an upper and a lower layer of the carrier material into a slit of which this slide fastener is to be sewn. An arm is mounted on the sewing machine and can pivot in a horizontal plane between a position in which the material and the slide fastener are placed onto the arm and maintained in a predetermined relationship relative to one another, and a second position in which the material and the slide fastener are supplied, while still being maintained in this predetermined relative position, to the feed dogs which engage the material and advance it as the sewing machine sews the slide fastener to the material.
